Allergic rhinitis in children: blocked nose, sneezing, sleep and asthma control.

Parents usually notice the obvious symptoms first: sneezing, blocked nose, runny nose, nose rubbing, itchy eyes or mouth breathing. What is easier to miss is the wider pattern — poor sleep, tired mornings, school focus problems, cough after lying down, snoring, exercise cough, frequent reliever use or asthma that keeps flaring despite inhalers.

What allergic rhinitis is — and what it is not.

Allergic rhinitis happens when the lining of the nose reacts to allergens such as dust mites, pollen, mold, animal dander or cockroach particles. It can cause sneezing, blocked nose, runny nose, itchy nose, itchy eyes, throat clearing, post-nasal drip and mouth breathing.

• It is not always infection, especially when symptoms repeat without fever and include itching, sneezing or watery eyes.
• It is not always “sinus” disease; many children with allergy have nasal blockage without bacterial sinus infection.
• It is not always harmless if sleep, school, activity, growth, behaviour, hearing or asthma control is affected.
• It is not diagnosed by one sneeze or one bad day. Duration, severity, triggers and impact matter.
• It should not lead to repeated antibiotics, oral steroids or decongestants without proper assessment.

Use the ARIA-style pattern: duration and impact.

A practical review separates occasional symptoms from persistent symptoms, and mild symptoms from symptoms that disturb the child’s life.

• Intermittent pattern: symptoms occur on fewer than four days per week or for less than four weeks.
• Persistent pattern: symptoms occur on four or more days per week and for more than four weeks.
• Mild impact: sleep, play, school and daily life are not clearly affected.
• Moderate-to-severe impact: sleep disturbance, daytime tiredness, school problems, activity limitation or quality-of-life impact is present.
• Asthma symptoms, frequent reliever use, exercise limitation or attacks should move the review beyond the nose alone.

Why GINA 2026 asthma review should include the nose.

A child with asthma symptoms should not be reviewed only through the inhaler prescription. GINA-style asthma care looks at current control and future risk, including triggers, comorbidities, inhaler technique, adherence and the written action plan. Allergic rhinitis is one of the common nose-lung problems that can make asthma feel harder to control.

• Blocked nose and mouth breathing can worsen sleep and daytime tiredness.
• Rhinitis can add cough, throat clearing and night symptoms that parents may confuse with asthma alone.
• Allergy triggers may affect both the nose and lungs on the same days.
• Frequent reliever use, night waking, activity limitation or attacks should prompt asthma control review, not only a nose-medicine change.
• Before stepping up asthma treatment, technique, adherence, triggers and rhinitis should be reviewed.
• After urgent-care asthma attacks or oral steroid courses, the nose and allergy pattern should be part of the risk review.

How allergic rhinitis may be evaluated.

• History: seasonal or year-round pattern, sleep, school, triggers, family allergy, asthma and eczema context.
• Symptom burden: blocked nose, sneezing, itching, eyes, mouth breathing, snoring and quality of life.
• Asthma review: cough, wheeze, exercise symptoms, reliever use, attacks, inhaler technique, adherence and action plan.
• Nasal examination when needed: turbinate swelling, discharge, septum issues, adenoids, nasal polyps, foreign body clues or sinus complications.
• Allergy testing only when the result would change the plan. A positive test shows sensitisation and must match the child’s history.
• Sleep review if snoring, pauses, gasping, restless sleep, morning headaches or daytime sleepiness are prominent.
• ENT, allergy/immunology or pulmonology referral if symptoms are severe, persistent, complicated, treatment-resistant, asthma-linked or sleep-linked.

Treatment choices need matching.

• Trigger reduction: focus on realistic, high-yield steps such as avoiding tobacco smoke, reducing dampness or mold, washing bedding appropriately, and targeting dust-mite, pet or pollen exposure only when the pattern fits.
• Saline: may help rinse irritants or mucus for some children, but it is not a substitute for assessing persistent blockage, snoring, asthma symptoms or red flags.
• Oral antihistamines: can help sneezing, itching and runny nose, especially in mild or intermittent symptoms. Less-sedating options are usually preferred when suitable.
• Intranasal antihistamines: may work quickly for nasal symptoms in selected children when age, availability and prescription advice fit.
• Intranasal corticosteroids: are often the most useful option for persistent blocked nose and overall nasal symptom control, but require correct technique and regular review.
• Fixed combination intranasal antihistamine plus corticosteroid sprays: may help selected children with more severe or uncontrolled symptoms when age-appropriate and prescribed.
• Montelukast: should not be a casual first-choice allergy medicine. It requires a clear reason and discussion of mental-health, sleep and behaviour warning signs.
• Allergen immunotherapy: can be considered for selected children with confirmed clinically relevant allergy and troublesome symptoms despite good standard care.
• Antibiotics and oral steroids: are not routine allergic rhinitis treatments and should not be repeated for a chronic blocked nose without a clear diagnosis.

Montelukast: the caution parents should not miss.

Montelukast may appear in allergy and asthma prescriptions, but it is not a harmless “simple allergy tablet.” For allergic rhinitis, it should usually be reserved for children who are not helped by, or cannot tolerate, other suitable allergy treatments. Parents should be counselled about possible mood, behaviour, sleep or mental-health changes and should know when to contact the clinician urgently.

• Discuss nightmares, sleep disturbance, irritability, anxiety, sadness, aggression, attention changes or unusual behaviour before and during treatment.
• Do not start, stop or restart montelukast casually without clinician guidance.
• If concerning mood, sleep or behaviour symptoms appear, contact the prescribing clinician promptly.
• If the child has self-harm thoughts, severe behavioural change or safety concerns, seek urgent in-person mental-health or emergency care.

What not to do blindly.

• Do not use repeated antibiotics for every blocked nose without evidence of bacterial infection.
• Do not use nasal decongestant sprays repeatedly or for long periods unless a clinician has clearly advised it.
• Do not keep changing allergy medicines without checking nasal spray technique, adherence and triggers.
• Do not ignore snoring, pauses in sleep, daytime sleepiness, morning headaches or poor school focus.
• Do not assume cough is only “post-nasal drip” if there is wheeze, exercise limitation, night symptoms, frequent reliever use or attacks.
• Do not stop asthma medicines just because nose allergy is identified.
• Do not start or stop montelukast without discussing mood, sleep and behaviour warning signs with the clinician.
• Do not step up asthma treatment blindly without checking rhinitis, trigger exposure, inhaler technique, spacer seal, adherence and action-plan clarity.
• Do not use video consultation for acute breathing distress, facial swelling with breathing symptoms, low oxygen or a child who appears seriously unwell.
